These tools I found useful when I had to investigate why report generation failed. Since report generation failed, I had no reports about ebuild diffs or package occurences. The new scripts, `diff_pkg.sh` and `occurences.sh`, allowed me to get these reports for the troublesome package.

##
|
|
## Prints a diff of a package in old and new scripts
|
|
## directories. Operates in one of two modes. First mode is an
|
|
## "ebuild" mode where it shows a diff of two ebuilds. The other mode
|
|
## is an "other" mode where it shows diffs of all non-ebuild files
|
|
## (ignoring Manifest files too).
|
|
##
|
|
## Parameters:
|
|
## -h: this help
|
|
## -r <name>: New package name (useful when package got renamed)
|
|
##
|
|
## Positional:
|
|
## 1: mode, "ebuild" (or "e") or "other" (or "o")
|
|
## 2: path to old scripts repository
|
|
## 3: path to new scripts repository
|
|
## 4: package name (but see -r flag too)
|
|
## 5: old version (for "ebuild" mode only)
|
|
## 6: new version (for "ebuild" mode only)
